Thank you for your reply, ive been through the fAQ, the MIT videos, and many of the threads several times. I am quite confident that I understand the concept of crystal formation, and why it is used as a form of purification, and also why it must be pretty close to pure prior to doing it.
I've seen the white snowball kind of crystallization, and the evenly distributed tiny shard crystals, and they all formed in a couple hours i guess, maybe more.
I guess my confusion has arisen from what I believe is a case of melted, (rather than dissolved) spice. If the spice is hot enough to begin to melt before dissolving it in NPS, is it safe to assume thats too hot? I'm assuming it is, based on what happens as it cools. But i would like to be sure I've made the correct assessment of an unsatisfactory procedure, so that the adjustments will improve the results. Basically I need to chose between lower solution temp with slightly more solvent, or insulating the thick viscous melted solution for slower cooling.
Everything i say is fictional, I just wanna be cool and fit in.
